What Is a Vapor Barrier & Why Do I Need One?

If your crawlspace is bare dirt, then you need a plastic vapor barrier installed to reduce the excess moisture from traveling into your home through the subfloor. A vapor barrier consists of sturdy sheets of black crawlspace Visqueen plastic spread out to cover the entire floor under your home and up the walls a few feet. The proper plastic thickness for durability is at least 6mil. These sheets provide crawl space encapsulation to block moisture from getting into your home through the subfloor.

Top Benefits of a Vapor Barrier for Your Crawlspace

In the Puget Sound area, it's vital to keep moisture out of your walls, floors, and ceilings during our cold winters. That's what a vapor retarder does.

  1. Better air quality in your home – you won’t be breathing mold spores, mildew, and contaminants from rodents. Plus, your home will smell fresh – not musty.
  2. With vapor barriers in place, rodents like rats and mice, along with bugs like common spiders, and even black widows, aren’t as likely to make their home in your crawl spaces. With the vapor barrier replacement or new installation, your crawlspace will be much cleaner and your home healthier.
  3. A properly installed vapor barrier protects your subfloor, wood beams, and entire structure from termites and wood-destroying carpenter ants.
  4. It helps protect wiring and cables, plus the sheeting shields plumbing and gives it some additional insulation during the chillier months.
  5. A sturdy vapor barrier provides humidity control and stabilizes the temperature of your home since cold damp air isn’t coming up from under your home. With energy efficiency, you’ll have lower utility costs.
  6. Installing a vapor barrier protects your investment in your home. You will have much less deferred maintenance costs when your crawlspace is clean and moisture-free.

That’s simple; you find a local licensed contractor like Envirosmart Solution that provides the services you need and has excellent reviews.

Reinforced polyethylene plastic sheeting (poly) of at least 6 mil thickness is the material most commonly used as a vapor barrier. While thinner plastic or regrind may be OK for short-term use, only reinforced virgin poly should be used for long-term applications like crawlspace vapor barriers.

Without a vapor barrier, the moisture that comes in through the soil can lead to electrical shorts, which is a fire hazard. That water can also cause your plumbing to rust and eventually break over time.
Installing a vapor barrier in your crawl space will keep the area dry and healthy.

In the Puget Sound area, it’s vital to keep moisture out of your walls, floors, and ceilings during our cold winters. That’s what a vapor retarder does.
You don’t want condensation inside your walls, floors, or other areas because that will ruin your insulation. Plus, moisture is a breeding ground for bacteria and mold. That’s why having a new vapor barrier in good condition is so important.

We recommend a full cleaning and sanitation of your space, along with a thorough inspection for standing water or rodent activity, before we install a new vapor barrier, although it depends on the space conditions.

After your new clean crawl space is clean and shiny, you’ll need a vapor retarder (vapor barrier) to keep it in good shape. The most common material used is 6-mil polyethylene plastic.

When is it time to replace my vapor barrier?

There are two reasons you might want to consider replacing your vapor barrier instead of simply repairing it. Either it is damaged beyond repair, and a replacement will save you time and money, or you realize that repairing a cheap vapor barrier is ineffective, and you want a more secure moisture protection system.

A professional home inspection will offer you an answer if you need better protection for controlling moisture and securing your property for years to come.

Top Reasons To Replace Your Vapor Barrier

When a vapor barrier is installed by a professional, it should last for years. But they don't last forever and do need replacement. If you're experiencing any of these problems, you should have your crawlspace checked to see if your vapor barrier needs repairs or replacement.

  • Rodents, bugs, and droppings in your home – these pests are coming from someplace, and the first place to check is from under the house. When your crawlspace is clean and encapsulated, rats, mice, and bugs won’t have access, and your indoor air will be healthier.
  • Excess water and moisture in your crawlspace – is there standing water under your house? If so, Envirosmart Solution can install a pump to get rid of the water, along with a new vapor barrier to keep the moisture from seeping into your home and ruining your health. Standing water from poor drainage or flooding causes wood damage and breeds mold.

Damaged vapor barrier repair – sometimes harm comes from pests, rodents, and contractors or repairmen who had to crawl under your home. If we can repair it, we’ll let you know. But sometimes, what’s there is just too old and deteriorated.

What You Need to Know About Your Crawl Space Vapor Barrier

Why is a Black Plastic Vapor Barrier Better?

Vapor barriers come in clear, white, and black plastic. But in damp Puget Sound, black is more effective at stopping moisture evaporation, compared with the white or transparent Visqueen. Clear plastic can sweat.

Dark colors are more efficient at preventing moisture evaporation, and they halt the growth of plants that might dwell beneath a home’s crawlspace. Plants and mold naturally emit moisture into the air, and that creates added dampness and condensation.

Black plastic sheeting creates a healthy and clean crawlspace. That, along with proper ventilation, is the key.

Envirosmart Solution always uses the industry’s highest-quality Visqueen sheeting products in all of our crawlspace vapor barrier installations or repairs. So, you can be confident your crawl space will be in good repair for years to come.
